Definitions

  • the invention relates to a system according to the preamble of the claim
  • Annular tunnel kilns have - based on the same Performance - the advantage of a smaller footprint compared to linear Tunnel kilns.
  • the disadvantage of the generic systems is that that large masses (especially the wagon platform) are heated need, resulting in high energy consumption and high loss of leads to unused heat. From DE 39 31 301 A1 it is known for burning pieces of porcelain or ceramic in a tunnel oven use, the tunnel floor is insulated and slotted and through the bottom slots a carrying the fired goods, especially plates Circulating conveyor with the stands of arranged on a chain Tripods protrude.
  • the invention has for its object to a generic system create that with simple and space-saving construction - both small Floor space requirements as well as relatively low height - an improved one Ratio of stocking weight / product mass to the mass of the Means of transport that must necessarily be heated with and thus works in an energy-saving manner, the same as both a dryer and can also be designed as a furnace and a furnace formation should have high thermal shock resistance and heat-related Changes in length in the transport system do not have an adverse effect should.
  • the bottom / furnace bottom 1 has one along of a circular ring, supported by columns 2 treatment tunnel in particular two longitudinal slots running parallel to one another 3. Below the longitudinal slots 3 run through rails 4 and 5 formed runways.
  • the rails 4 form an outer closed Circle, the rails 5 a concentric, also closed inner circle.
  • rollers 6 of parts of a chassis ring 7 and 8 supported On the rails 4 and 5 are rollers 6 of parts of a chassis ring 7 and 8 supported, the parts of the chassis ring 7 by means of screwed flanges 9 to an outer ring body / chassis ring and the parts of the chassis 8 by means of screwed flanges 10 into one inner ring body / chassis ring are connected.
  • the chassis 7 support vertical stands or uprights 11, the chassis 8 uprights 12. All uprights 11, 12 protrude through the associated longitudinal slots in the tunnel body 3 in the floor 1 in the treatment room, in particular the furnace room.
  • sealing groove 13 For sealing is below and on both sides of the longitudinal slots 3 in the furnace floor 1 each arranged a circumferentially closed sealing groove 13, the is filled with liquid (water, oil), zircon sand or the like.
  • liquid water, oil
  • zircon sand or the like.
  • the slots 3 are also expanded upwards and are therein attached to the uprights 11, 12 boxes 15 guided with a spray compound 16 are filled.
  • the drive shown in FIGS. 3 and 5 of the outer chassis ring takes place via an endless chain 20, which is in the U-shaped guides 21 of the Upright 11 is held.
  • Sprockets 22, which are mounted on bearing blocks 23 are, keep the chain 20 in the guides 21.
  • guide rollers 24 are supported for the upright 11.
  • the drive is the one receiving the products Transport trolleys arranged outside the hot furnace area and particularly simple. All you need is a chassis ring are driven, the other chassis ring is driven by the pull rods located inside the furnace. Come this Tie rods in the high temperature area, where the tensile strength of the Materials naturally reduced, so they are due to their thermal expansion automatically relieved and those tie rods that are in at this time the heating or cooling zone or outside the oven at all, take over the traction.
